Concern over Hernandez safety was a factor in moving the ex-Patriots star into a cell where he will not be allowed to mix with the general jail population, Sheriff Thomas Hodgson said Monday.

"The reason for this move is simply to protect him. We wouldn't want some inmate trying to get any notoriety by attempting to harm Aaron Hernandez," Hodgson said, adding that contrary to reports, Hernandez is not in solitary confinement.

Hodgson told NewsCenter 5 inmates are always looking to raise their own status by taking on a high-profile inmate.

Prosecutors said Hernandez orchestrated Odin Lloyd's execution-style shooting near Hernandez's North Attleborough home on June 17. They say it happened after the two went to a nightclub a few days earlier and Lloyd, 27, spoke to people Hernandez didn't want him talking to.

In jail, Hodgson said Hernandez, who can be out of his cell for three hours a day, has been polite and adjusting well.

"For a man who has gone from 7,000-square-feet to a small cell, he is doing very well and seems to be taking the situation great. He is very respectful and calm," Hodgson said.

Hernandez has had no visitors, according to Hodgson.

Prosecutors are still trying to gather evidence against Hernandez and his alleged associates Ernest Wallace and Carlos Ortiz.

They renewed a call Monday night for the public's help in finding a broken driver's-side rear view mirror from a silver or gray 2013 Nissan Altima.

Without offering explanation as to its importance, they said it might be found along the route from Odin Lloyd's Dorchester home to Hernandez's North Attleborough home.

Wallace, who was arrested in Florida, agreed Monday to return to Massachusetts to face a charge in the murder case;

Wallace, 41, faces a charge of accessory after the fact of murder. Wallace turned himself in at a Miramar, Fla., police station last week.

In a statement, prosecutors in Bristol County, Mass., said they have 10 days to pick him up. They gave no indication when they would do so.
